Use of barriers to limit movement of parasitoids of Lygus spp
1998
Jackson, C.G. | Debolt, J.W. | Jones, W.A.
Alfalfa plots enclosed by 1.9 m high plastic barriers limited the movement of Lygus spp. parasitoids released inside the enclosures. Leiophron uniformis (Gahan), a parasitoid of Lygus spp. nymphs, was successfully contained inside the enclosures. Parasitism of nymphs inside the enclosures was between 20 - 29% with levels of only 0 - 5.6% outside, and 0 - 0.3% inside enclosures without parasitoid releases. Some Anaphes iole (Girault) moved over the barriers, but parasitism of Lygus spp. eggs averaged 43% inside release enclosures, 20 -21% outside, and 13% inside enclosures without parasitoid releases.
